The Gmail™ application, Google Maps™ application, Instagram™ application, Facebook™ application, and/or Kakao Talk™ application included in the applications 211 may be third party applications. The third party application may be an application downloaded from another electronic device.

The setting application 222 may control, for example, the power (turning on or turning off) or the functions (the brightness, resolution, or focus of the display device 160 or the camera module 180) of an external electronic device that communicates with the electronic device 101 or some elements (e.g., the display device 160 or the camera module 180) thereof. The setting application 222 may support installation, deletion, or updating of an application that operates in an external electronic device.

The applications 211 and the setting application 222 included in the application layer 201 may draw at least one layer based on the resolution of a display area of the display (e.g., the display device 160).

According to various embodiments, the applications 211 and the setting application 222 included in the application layer 201 may draw at least one layer based on the resolution of a display area of the display (e.g., the display device 160), using a drawing library (e.g., view).

The applications 211 and/or the setting application 222 included in the application layer 201 may include an event associated with a frequency (or information associated with a refresh rate) according to a scenario.

The event associated with a frequency (or information associated with a refresh rate) may be stored in advance in each of the applications 211 and/or setting application 222, and may be set for each of the applications 211 and/or setting application 222 by a user input.

If an event associated with a frequency (or information associated with a refresh rate) occurs from the software related to a system, the electronic device 101 may transfer the event associated with a frequency (or information associated with a refresh rate) to the high speed screen control module 212 and/or high speed operating module 213 of the first framework layer 202.

The electronic device 101 may designate in advance and configure an event associated with a frequency (or information associated with a refresh rate) of a display (e.g., the display device 160) using the setting application 222.

According to various embodiments, the electronic device 101 may designate in advance and configure an event associated with a frequency (or information associated with a refresh rate) of each of the applications 211 using the setting application 222.

According to various embodiments, the electronic device 101 may designate in advance and configure an event associated with a frequency (or information associated with a refresh rate) of a game application management module 2142 (e.g., a game booster setting application) using the setting application 222.

According to various embodiments, the electronic device 101 may designate in advance and configure an event associated with a frequency (or information associated with a refresh rate) of a camera application management module 2141 using the setting application 222.

According to various embodiments, the electronic device 101 may include a normal speed mode and/or a high speed mode for a refresh rate. For example, the normal speed mode may be a mode for operating the refresh rate of a display (e.g., the display device 160) included in the electronic device 101 to be less than or equal to a first frequency (e.g., 60 Hz). The high speed mode may be a mode for operating the refresh rate of a display (e.g., the display device 160) included in the electronic device 101 to be greater than or equal to the first frequency (e.g., 60 Hz) and/or less than or equal to a second frequency (e.g., 120 Hz).

According to various embodiments, if the electronic device 101 is in the normal speed mode, the electronic device 101 may support all resolutions that the display (e.g., the display device 160) is capable of implementing.

According to various embodiments, the resolutions that the display (e.g., the display device 160) is capable of implementing may include, for example, a wide quad high definition (WQHD) resolution, a full high definition (FHD) resolution, and/or a high definition (HD) resolution. If the electronic device 101 is in the normal speed mode, the electronic device 101 may support a wide quad high definition (WQHD) resolution, a full high definition (FHD) resolution, and/or a high definition (HD) resolution.

According to various embodiments, if the electronic device 101 is in the high speed mode in association with a refresh rate, the electronic device 101 may support a resolution which is less than or equal to a predetermined resolution among all resolutions that the display (e.g., the display device 160) is capable of implementing. If the electronic device 101 is in the high speed mode, the electronic device 101 may support a full high definition (FHD) resolution and/or a high definition (HD) resolution.

According to various embodiments, the electronic device 101 may change the normal speed mode and/or high speed mode under the control of the processor 120. The electronic device 101 may change the normal speed mode and/or high speed mode according to user selection. The electronic device 101 may include the setting application 222 via which a user is capable of selecting the normal speed mode and/or high speed mode. The electronic device 101 may provide a user interface via which a user is capable of selecting the normal speed mode and/or high speed mode on the display (e.g., the display device 160).

According to various embodiments, the electronic device 101 may change a refresh rate when a mode is changed between the normal speed mode and/or the high speed mode. If a refresh rate is changed according to a transition between the normal speed mode and/or high speed mode, the electronic device 101 may terminate execution of an application and may perform transition according to the selected refresh rate. If a refresh rate is changed according to a transition between the normal speed mode and/or high speed mode, the electronic device 101 may maintain execution of an application and perform transition according to the selected refresh rate.

The electronic device 101 may process a first frame (frame 1) to be black when changing a refresh rate according to a transition between the normal speed mode and/or high speed mode. When transition is performed between the normal speed mode and/or high speed mode, the length of a vertical front porch (VFP) may become longer and a difference in brightness may occur. The difference in brightness may be recognized as the flicker of a screen. According to various embodiments, when changing a refresh rate according to a transition between the normal speed mode and/or high speed mode, the electronic device 101 may process the first frame (frame 1) to be black, and may reduce the flicker of a screen which occurs when the refresh rate of the electronic device 101 is changed.

The first framework layer 202 may include the high speed screen control module 212 (a high speed window manager), the high speed screen operating module 213 (a high speed display manager), an application management module 214, a sensor control module 215, a heat generation control module 216, and/or power saving module 217.

The high speed screen control module 212 (high speed window manager) may perform a high speed screen control operation based on a frequency event received from the application layer 201.

According to various embodiments, the high speed screen control module 212 may determine a refresh rate according to a policy. If the electronic device 101 performs a screen transition of an application that is being executed and/or the screen that the electronic device 101 is displaying corresponds to an animation screen operation, the high speed screen control module 212 may determine a refresh rate to be less than or equal to the second frequency (e.g., 120 Hz), and may control the display (e.g., the display device 120).

According to various embodiments, if an application that is being executed is registered as an application that operates at a non-high refresh rate, the high speed screen control module 212 may determine a refresh rate to be less than or equal to the first frequency (e.g., 60 Hz) and may control the display (e.g., the display device 120). Each of the applications 211 may include a separate refresh rate and/or a separate package when being installed or registered in the electronic device 101. An application may be installed or registered in the electronic device 101 as an application operating at a non-high refresh rate and/or as a separate package.

According to various embodiments, if an application that is being executed declares a refresh rate, and if the application that is being executed is registered in the application management module 214 as an application operating at a separate fixed refresh rate and/or a package, the high speed screen control module 212 may control the display (e.g., the display device 120) at the registered fixed refresh rate. An application may be installed or registered in the electronic device 101 as an application operating at a fixed refresh rate and/or as a separate package.

According to various embodiment, if an application that is being executed is an application that is determined, selected, and/or configured as an application operating at a high refresh rate in the setting applications 222, the high speed screen control module 212 may determine a refresh rate to be less than or equal to the second frequency (e.g., 120 Hz) and may control the display (e.g., the display device 120).

According to various embodiments, if an application that is being executed is at least one of a lock screen, a home screen, settings, and a navigation bar, the high speed screen control module 212 may determine a refresh rate based on a priority order, and may control the display (e.g., the display device 120).

For example, if an application that is being executed is a lock screen, the lock screen application may perform a video wall paper animation operation, and may perform an animation operation that changes the lock screen to a home screen.

For example, if an application that is being executed is a home screen, the home screen application may perform an application launch animation, and may perform a page transition animation.

For example, if an application that is being executed is settings, the setting application 222 may perform a list navigation animation, and a depth-in-and-out animation. A depth-in-and-out animation operation may be an operation (depth in) of further displaying information when an item displayed on a list is selected or an operation (depth-out) of displaying previous information of displayed information.

For example, if an application that is being executed is a navigation bar, the application may perform a recent animation, a home screen animation, and a back navigation animation. The recent animation may be an animation that reduces an execution screen associated with a recently executed application and displays at least one reduced execution screen. The home screen animation may be an animation that changes an application execution screen to a home screen. The back navigation animation may be an animation that displays the screen of a previous stage.

The commands associated with the application management module 214 may be stored in the memory 130, and may be performed under the control of the processor 120.

The application management module 214 may transfer, to the high speed screen control module 212, information associated with the package of an application that is registered as a package in the application management module 214 and information associated with a refresh rate requested by the application, from among the applications 211.

If the brightness and/or illuminance of the display (e.g., the display device 160) or the electronic device 101 is greater than or equal to a predetermined brightness and/or illuminance, the sensor control module 215 may request the high speed screen operating module 213 to operate a refresh rate to be less than or equal to the first frequency (e.g., 60 Hz) and/or the second frequency (e.g., 120 Hz).

If the brightness and/or illuminance of the display (e.g., the display device 160) or the electronic device 101 is less than or equal to a predetermined brightness and/or illuminance, the sensor control module 215 may request the high speed screen operating module 213 to operate a refresh rate to be less than or equal to the first frequency (e.g., 60 Hz).

The heat generation control module 216 may receive information associated with the battery state and the heat generation of the electronic device 101. The heat generation control module 216 may transmit the information associated with the heat generation of the electronic device 101 and/or the information associated with the battery 189 to the high speed screen operating module 213.

If the heat generation state of the electronic device 101 is greater than or equal to a predetermined temperature, the heat generation control module 216 may request the high speed screen operating module 213 to operate a refresh rate be less than or equal to the first frequency (e.g., 60 Hz).
